What might be the evolutionary advantage of allergic reactions? (Hint: Are there harmful substances or organisms that might provoke allergic reactions?)
From: "Towards a universal flu vaccine"
Each
year,
the flu vaccine includes antigens from two strains of Influenza A and two
strains of Influenza B. These antigens are from the head of the H spikes an area that
sticks out from the virus and so, is very easy for human immune cells to detect.
However, the problem with using the head of the H spike as an antigen is...
O The H spike head mutates very rapidly, so quickly changes to forms not recognized by human
immune cells.
O The H spike head is exposed on the surface of the virus for only a short period of time.
Viruses quickly pull the H spikes back inside the virus, shiclding them from human immune
cells.
O The H spike head is often too big for the human immune cells to attack.
O The H spike head is often too small for the human immune cells to bind to.
Using arrows identify at least 2 different WBC types. Ignore the 3 splattered ones. One of these cell types is in a majority. From your learning, (a) Which lineage do they belong to? (b) State ONE 'infectious' condition in which they are likely to be in abundance, and why? (c) how would we go about differentiating them at their surface marker level?

In other words, there appears to be selection for maintaining hundreds to thousands of different alleles of each MHC gene in the population. This notion is based on the observation that nucleotide differences between alleles that lead to amino acid substitutions are more frequent than those that are silent substitutions (i.e., not changing the amino acid sequence of the protein). In addition, the positions within the MHC protein where most of the allelic sequence variation occurs are not randomly distributed, but are concentrated in certain regions of the MHC protein. This latter point indicates: That some nucleotide sequences within the MHC genes are hot-spots for mutation That MHC genes are more susceptible to point mutations than to larger nucleotide deletions That MHC allelic polymorphism has been driven by selection for diversity in peptide binding specificity That MHC genes…arrow_forwardWhich of the following statement regarding the whole-pathogen vaccine is/are correct (B) Live attenuated whole-pathogen vaccines are more effective to elicit a robust immune response, and often a single dose is sufficient.
